native::x86_capabilities Struct Reference

Collaboration diagram for native::x86_capabilities:

Classes
struct	raw_observations
	CPUID query inputs retained for diagnostics, not a second admission source. More...

Public Attributes
isa< x86 >	present {}
	Features whose queries succeeded and reported support; no compiler closure.
isa< x86 >	observed {}
	Features whose CPUID leaves were available, whether present or absent.
std::uint64_t	xcr0 = 0
	OS-enabled vector state. Used only when xcr0_observed is true.
bool	xcr0_observed = false
	True after XSAVE/OSXSAVE permit XGETBV and its result was captured.
raw_observations	raw {}
	Diagnostic snapshot; editing it does not update present/observed or XCR0.
std::array< char, 13 >	vendor_id {}
	Exact CPUID vendor identifier, followed by a zero terminator.
enum cpu_vendor	vendor = cpu_vendor::unknown
	Classification of vendor_id; it does not establish instruction support.

Detailed Description

Normalized features of the executing logical CPU, not every CPU in a system. Admission reads present/observed and XCR0; raw registers are diagnostic only.
